Don't draw zero value label

[liebeskind]

Any know a way to not draw the value labels that are 'zero' in a horizontal bar graph?

NSNumberFormatter is a very strong factory.

Meaning you can set zeroSymbol to "", which by default is "0"

Or, make a subclass of NSNumberFormatter, and format the numbers however you like.

Brilliant! That worked. Thanks Daniel. For others that are interested in doing something similar, here is my fairly simple NSNumberFormatter subclass.

class NoStyleFormatter: NSNumberFormatter {
    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override init() {
        super.init()
        self.numberStyle = .NoStyle
        self.zeroSymbol = ""
    }

    // Swift 1.2 or above
    static let sharedInstance = NoStyleFormatter()
}

Man that's over-complex.
Just do:

var noZeroFormatter = NSNumberFormatter()
noZeroFormatter.zeroSymbol = ""

You can subclass - but for changes that you don't have properties for. Luckily you have properties for anything you can dream about...
